The pertinent part of the log shows that the mount failed because /tank directory was not empty which is expected behaviour.

So, how to upgrade?

[Colin Ian King (colin-king)]

From the error that I see, /tank is not empty. What is in that directory?

[Lorenzo (hannibal80)]

Everything stored by zfs. It's the mount point. So, I can't free it up, I can unmount but is this the correct procedure to upgrade? I definitely don't want to lose my data.

[Lorenzo (hannibal80)]

Hello Sir,
I understand it can be quite weird to bring this up after some 6 years...
So I would totally understand if you could not resume this conversation.

My server, which is a home server, is still in the same situation it was at
the time. Upgrades limited to 16.04 are installed except for zfs because of
the problem I mentioned in this case.

The /tank directory is where my zpool is mounted. Should I unmount it
before proceeding with updates?

Thanks again and beg your pardon for the disturb.

Regards,
Lorenzo
